141236-32-0 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 141236-32-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,2,3 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 141236-32:
(8*1)+(7*4)+(6*1)+(5*2)+(4*3)+(3*6)+(2*3)+(1*2)=90
90 % 10 = 0
So 141236-32-0 is a valid CAS Registry Number.

Alkaline metallic reagent-catalyzed hydrocarbocyclization reaction of various active methine compounds having an unactivated 4-alkynyl or allenyl group

Kitagawa, Osamu,Suzuki, Takashi,Fujiwara, Hiroki,Fujita, Masao,Taguchi, Takeo

, p. 4585 - 4588 (1999)

On using a catalytic mount of NaH or n-BuLi, hydrocarbocyclization reaction of various active methine compounds having an unactivated 4-pentynyl or 3,4-pentadienyl group proceeded through proton transfer mechanism to give methylenecyclopentane derivatives

An efficient and general microwave-assisted copper-catalyzed Conia-ene reaction of terminal and internal alkynes tethered to a wide variety of carbonucleophiles

Montel, Sonia,Bouyssi, Didier,Balme, Genevieve

experimental part, p. 2315 - 2320 (2010/11/05)

This paper describes a highly efficient, microwave-assisted, Conia-ene reaction of alkynes bearing a stabilizing carbon nucleophile. The reaction, catalyzed by a commercially available copper catalyst, proceeds under neutral conditions and is generally applicable even to less reactive nucleophiles such as malonate, cyanoacetate, and sulfonylacetate derivatives. This copper-mediated cycloisomerization is also applicable to internal unactivated alkynes leading exclusively to the corresponding 5-membererd products having an E-olefinic chemistry.

Intramolecular carbotitanation reaction of active methine compounds having an unactivated alkyne mediated by TiCl4-Et3N

Kitagawa, Osamu,Suzuki, Takashi,Inoue, Tadashi,Taguchi, Takeo

, p. 7357 - 7360 (2007/10/03)

In the presence of TiCl4 and Et3N, intramolecular carbotitanation reaction of active methine compounds having an unactivated 4-alkynyl group proceeds in a highly cis-selective manner to give methylenecyclopentane derivatives in good

Carbocyclization reaction of active methine compounds with unactivated alkenyl or alkynyl groups mediated by TiCl4-Et3N

Kitagawa, Osamu,Suzuki, Takashi,Inoue, Tadashi,Watanabe, Yoko,Taguchi, Takeo

, p. 9470 - 9475 (2007/10/03)

In the presence of TiCl4, Et3N, and I2, iodocarbocyclization reaction of various active methine compounds having alkenyl groups gave iodocycloalkane derivatives in good yields. On the other hand, TiCl4 and Etsu

SYNTHESIS OF ETHYNYLIDENE CYCLOPENTANES BY A CYCLISATION CATALYZED BY THE SIMULTANEOUS PRESENCE OF PALLADIUM (0) AND COPPER (I)

Boussy, Didier,Balme, Genevieve,Gore, Jacques

, p. 6541 - 6544 (2007/10/02)

Ethynylidene cyclopentanes 3 can be formed in 35-71percent yield from the reaction of the enolates of compounds such as δ-acetylenic malonates with 1-halogeno-1-alkynes.This reaction requires catalysis by both palladium (0) and copper (I) species.
